    I agree
    
      Any wordsmiths that can figure out how?

    The problem is that we should be able to creare a SC so that no particular
    kind of media is left out.
    
    I think we should find the way not to specify fixed numbers, but I realize
    it's almost impossible if we want to keep the SC testable; also the 20 db
    threshold is a fixed number, but in that particular case, I feel that it's a
    reasonable compromise.
    
    Best regards,
    
    Roberto Castaldo

    Better
    
    But I think this would still eliminate all war films. 
    
    It is level 3 but… 
    
     
    
    I wonder if we can figure a way to get what we want without catching so much
    else that it would be ok to leave out.

    I propose we rewrite:
    
     
    
    Level 3 Success Criteria for Guideline 1.5 
     
    <current>
    1.      Audio content does not contain background sounds OR the background
    sounds are at least 20 decibels lower than the foreground audio content with
    the exception of occasional short sounds. [V] </current>
     
    <proposed>
    1.      Audio content does not contain background sounds OR the background
    sounds are at least 20 decibels lower than the foreground audio content with
    the exception of occasional short sounds. (where “short” may be defined as
    less that 10 seconds and “occasional” may be defined as occurring more
    frequently than once every 10 minutes.) [V] </proposed>
     
     
     
    In an attempt to make our guidelines testable, I chose 10 seconds as the as
    the threshold for the word “short” to allow for what the movie industry
    would describe as an airplane passing overhead or a bomb exploding. I chose
    10 minutes as the threshold for “occasional” because I think any more
    frequency than that would be quite distracting and difficult to follow
